The present invention provides a method for diagnosing schizophrenia, and a schizophrenia diagnostic reagent or device for use in the method. The present invention further provides a therapeutic or ameliorating agent for schizophrenia, which is effective for the treatment or amelioration of schizophrenia. The therapeutic or ameliorating agent for schizophrenia contains a carbonyl scavenger or a carbonyl-modified protein formation inhibitor as an active ingredient. The method for diagnosing schizophrenia according to the present invention includes measuring at least one parameter in a subject, the parameter being selected from the group consisting of: (1) a genetic abnormality of glyoxalase I gene; (2) the expression level or activity of glyoxalase I in a biological sample; (3) the amount of a carbonyl compound or a carbonyl-modified protein that is a protein modified with the carbonyl compound; and (4) the amount of pyridoxal in a biological sample.

[PROBLEMS] To provide a inhibitor of protein modification products formation capable of inhibiting of vitamin B6 deficiency disease as a side effect, especially a renal protective agent. [MEANS FOR SOLVING PROBLEMS] There is provided a use, as an active ingredient, of any of free or salt-form compounds of either of the formulae: (I) (II) [wherein R1 is substituted or unsubstituted aromatic ring; and each of R2, R3 and R4 is a hydrogen atom or monovalent organic group, or alternatively R2 and R3 cooperate to form a condensed ring or R3 and R4 cooperate to represent a divalent organic group, provided that R3 and R4 are not simulataneously hydrogen atoms].

The present invention relates to a method for diagnosing schizophrenia comprising measuring at least one parameter in a subject, the parameter being selected from the group consisting of (1) a genetic abnormality of glyoxalase I gene, (2) the expression level or activity of glyoxalase I in a biological sample, (3) the amount of a carbonyl-modified protein that is a protein modified with the carbonyl-compound, preferably pentosidine, in a biological sample, and (4) the amount of pyridoxal in a biological sample. The present further relates to a primer, a probe and a reagent for use in said method, as well as an AGE-reader and its use for measuring the amount of carbonyl-modified proteins.
